gamification to a online course(e learning is working)

we have a website running with paid online courses with a my sql data base.

at this first stage we want to adda routine to add any student course page :

1-a percentage bar to showing how much of the whole course the student has [url removed, login to view] course has several videos.

2-add 5 custom badges for some [url removed, login to view] design will will not be part of the job,we will furnish them.

so as the student goes through the courses showing a percentage bar he earnes badges ,pretty like khan academy but simpler than that.

later we will have more work but it will be the beggining to get trust.

There is a sample course with 9 videos and same support stuff to download. Percentage bar will be based only on watched videos.badges : there are xis videos on this course,and you watched ypsilon videos, meaning z% and shows it on % bar or % circle.then as the student continue his course it will add 5 badges thorugh the course.example he gets 10% earns one, gets another 25% earn another, gets another 50% earn another gets 75% another one till 100% .when he got the badge a message saying"great job keep on the good work"or something like this.pretty much like khanacademy.com
